Metaplexis is a genus of flowering plants in the family Apocynaceae, first described as a genus in 1810. As presently conceived, it contains two known species, both native to east Asia.[1][2]
Description
Metaplexis plants are vines that reach 8 m high; are rhizomatous and have underground woody organs that constitute a pattern. Leaf-blades are herbaceous, about 5–10 cm long and 4.6 cm wide, ovate, basally cordate, acute apex attenuated, adaxial glabrous and are abaxially sparsely pubescent.[2]
The inflorescences are extra-axillary, solitary, almost as long as the adjacent leaves. The plants have 6-20 flowers, simple, with the peduncle longer than the pedicels which are practically obsolete and slightly pubescent on the whole surface.[2]
